DUBOS, Céline et al. Identification of Lactobacillus spp. in colostrum from Chilean mothers. ALAN [online]. 2011, vol.61, n.1, pp.66-68. ISSN 0004-0622.

The biodiversity of Lactobacillus spp. in colostrum samples from 116 Chilean mothers was analyzed by PCR and 16S rDNA sequencing. Lactobacilli were isolated in 55.3% of the samples, with concentrations of 3.33 ± 0.55 (log CFU/ml). The predominant species were L. plantarum (64%), L. fermentum (16%) and L. pentosus (9%). 28% of the isolated strains were resistant to gastric pH and bile salts, suggesting that they could be used as probiotics.
